Question

Solve by using the addition method.. Provide the solution set:
3x^2-5y^2=-33
2x^2+5y^2=35

Answer 1

when you add these 2 equations the terms in y disappear to give
5x^2 = 2

solve for x (there will be 2 solutions)
and plug these into one of the original equations to find the values of y.

Answer 2

can you finish this or need more help?

Answer 3

But now I have another one that the y values do not disappear?!

Answer 4

And I dont get them!!

Answer 5

ok post it

Answer 6

2x^2-3y^2=-19
3x^2+2y^2-30

Answer 7

ok
to do this you multiply equation 1 by 2 and equation 2 by 3 to give

4x^2 - 6y^2 = -38
9x^2 + 6y^2 = 90

is that = 30 in second equation?

Answer 8

yes sorry
lol

Answer 9

ok
so if you add these 2 equations you will eliminate y

Answer 10

when you multiply equations be sure to multiply each term

Answer 11

Thanks!!!!! I see it now!!!

Answer 12

good

Answer 13

that is what this website is for.

Answer 14

So, would the answer be 2,3???
